Common questions

Is Toolcall safe?

It passed 5 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 4 months ago, and the latest version (1.0.0) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

Toolcall MCP

30 pay-per-call APIs for AI agents, over MCP. Compliance, trade, safety, web, and data tools an agent can call directly. No account, no API key. Each call costs a few cents in USDC on Base via the x402 protocol, and the calling client pays automatically when it supports x402.

  • Remote MCP endpoint: https://toolcall.click/mcp (Streamable HTTP)
  • Catalog / manifest: https://toolcall.click/ and https://toolcall.click/.well-known/x402
  • OpenAPI: https://toolcall.click/openapi.json

What you get

One MCP server, 30 tools spanning things agents actually need but that are annoying to wire up: official sanctions/AML screening, HS-code customs classification, chemical safety, FDA drug/device intelligence, electronic-component pricing, SEC financials, and clean web tooling (search, reader, screenshot, tech-stack, archive history). Every tool is a single call that aggregates authoritative sources and returns clean JSON.

Connect

Any MCP client that supports remote Streamable HTTP servers

Point it at:

https://toolcall.click/mcp
Claude Desktop / Cursor / stdio-only clients

Bridge the remote server to stdio with mcp-remote:

{

"mcpServers": { "toolcall": { "command": "npx", "args": ["-y", "mcp-remote", "https://toolcall.click/mcp"] } } }

Paying for calls

Tools are priced per call (see table). The payment model is client-pays: calling a tool without payment returns the exact price and x402 payment requirements in the result's _meta["x402/payment-required"] field. An x402-capable client signs a USDC payment on Base (gasless, EIP-3009) and retries with the signed payload in params._meta["x402/payment"]. The server never holds or forwards funds — payment goes straight to the tool operator's wallet.

You can also call any tool over plain HTTP with a standard x402 client (e.g. x402-fetch, x402-axios, or the Coinbase CDP Bazaar): a bare request returns HTTP 402 with payment requirements; pay and retry the same URL.
